FIELD OF THE INVENTION

The present invention relates to the ocean wave energy exploiting and storing device.

BACKGROUND OF THE INVENTION

It is now possible to exploit energy from ocean waves for electricity generation by floating buoy which is a device with buoy-attached lever arm and there are hydraulic cylinders attached to lever arm for oil pumping or floating buoy is attached to the axle head of hydraulic cylinders. Ocean waves will lift the buoy up and down to pump oil to an accumulator pressed by pressure generating gas to provide energy directly for the turbine or the hydraulic motor. The hydraulic motor provides energy for the turbine to generate electricity by rotation, or for the hydraulic cylinders for its pulling and pushing movement upon the equipment clusters which are equipped with permanent magnets to generate electricity through oscillation.

The weaknesses of current devices include incapacity of energy storage, low level of generated pressure and low stability, which lead to low efficiency in electricity generation.

SUMMARY OF THE INVENTION

Therefore, the purpose of the present invention is to improve the exploitation efficiency to store energy for electricity generation when there is no wave.

To achieve the above-mentioned purpose, the ocean wave energy exploiting device has been invented as follows:

The hollow pillar of the device is installed on the sea bed with the head emerging out of the water. The pillar is equipped with two work platforms of which one is installed with buoys and oil-pumping hydraulic cylinders and the other with oil tanks, hydraulic motors, turbines, electric distribution boards and other relevant equipment. The distinguished feature of the device is that on the outer side of the pillar, there are slots to install platform-lifting hydraulic cylinders and a base to support the platform. The hollow section of the pillar is the position to install the weight-loaded type accumulator. The two separated platforms installed to the pillar work independently.

Since the accumulator is installed within the pillar, the capacity of the accumulator is enhanced and the weight of the second work platform affects the axle head of the accumulator. Due to the weight of the second platform and major equipment on the axle head of the accumulator, the pressure therein is always stabilized at a high level.

DETAILED DESCRIPTION OF THE INVENTION

As illustrated in FIG. 1, the ocean wave energy exploiting and storing device includes: At least one hollow pillar (1) installed on the ocean bed with the head emerging out of the sea water. The outer surface of the pillar is made of salt resistant material with slots to install hydraulic cylinders (2) to lift the first platform (3) and a base to support the first platform (3). The pillar is also the cover for a weight-loaded type accumulator. This high volume accumulator (4) is installed inside the pillar. The center axle of the accumulator is higher than the pillar head to install the second platform. This second floor always weight on the axle head of the accumulator to press the oil for pressure. The pillar is not only used to support the work platforms but also the location to install the high volume accumulator.

The first platform (3) cover the pillar head above the sea level and can move up and down thanks to the operation of the hydraulic cylinder (2). The cylinder (2) is energized from the accumulator (4) via a pipe, the control valve raise and fall by the tidal cycles. There is at least one lever arm cluster (6) with one end attached to the first platform via a swivel joint (7). On the lever arm, there is another swivel joint (8) to connect it with one end of the hydraulic cylinder (9). The hydraulic cylinder (9), at the other end, is connected to the platform (3), also through a swivel joint (10). The oil provided for the hydraulic cylinder (9) is from the oil tank (11) via a pipeline with check valve. The level arm (6) is equipped with a buoy (12) on the other end. Ocean waves lift the buoy (12) up and down, pushing the level arm (6) to make the hydraulic cylinder (9) work and pump oil into the accumulator (4) via a pipeline and a check valve.

The second platform (13) is placed on the head of the pressing axle (5) of the accumulator (4) above the first one (3). The distance between the two platform provides enough space for the first platform (3) to move up and down, as controlled by the hydraulic cylinder (2) with tidal movement.

When the buoy (12) moves up and down with the ocean wave and push the level arm (6), forcing the hydraulic cylinder (9) to pump oil to the accumulator (4) via the pipe line and the check valve, the second platform (13) will be lifted upward by the axle (5) of the accumulator (4). The weight of the second platform (13) always press onto the axle of (5) of the accumulator (4) to create a stable pressure. The oil flow with high pressure in the accumulator (4) generate power and transfer it to the hydraulic cylinders (2) and (9) and the hydraulic motor (14) via the control valves and the pipelines. The hydraulic motor (14) then rotate the acceleration box (15) to energize the turbine (16) to generate electricity. The high pressure oil provided for the cylinders (2) and (9) and the hydraulic motor (14) from the accumulator (4) will then be returned to the oil tank (11) where it is processed and cooled before being transferred to the cylinder (9) again to start a new cycle. With the weight of the second floor loading on the axle (5) of the accumulator (4), a high stable pressure will be created as a huge source of instant energy for the effective operation of the turbine (16). Because of the high capacity and the high pressure of the accumulator (4), the energy reserved in it is still sufficient for the hydraulic cylinders, the hydraulic motor and the turbine to generate electricity.
